Articulated, multi-part assembly M142 HIMARS Rocket Launcher, fully modular

Below are the part diagrams and installation steps for the model. There are quite a few parts, and since it's a fused deposition printed part, it also includes some Print in Place articulated parts. Therefore, assembly requires some prior experience

Before installation, please carefully review all the images below. These are my installation steps, which include some installation instructions and important notes. Incorrect installation steps will prevent successful assembly

The upper and lower door hinges, shown in blue in the image above, are Print in Place articulated parts. When installing and gluing, pay close attention to their correct position. Do not apply glue everywhere. Only apply glue to the contacting areas of the door, hinge, and front three parts

The three crossbeams in the two consecutive images above are different, so pay close attention to their installation positions. If installed incorrectly, the fuel tank and storage box cannot be attached

The two consecutive images above illustrate the installation of the artillery's movable rails. During installation, first slide them into the bottom of the casing's rail groove until they are properly seated. Afterward, glue the transverse connecting beams of the two rails. This method ensures smooth movement when the parts slide against each other

Important: The parts shown in the three images above are Print in Place articulated parts. After printing, please manually articulate them first. As this is a fused deposition printing method, slight adhesions are inevitable during the printing process
